Subject Re: Long delay in listDomains API response
Date Sun, 06 Nov 2016 18:35:24 GMT
Hi Wei,

Thanks for your reply. Is it possible for us to remove the resource
limitation feature -- any global settings that we can set to turn this off?
If not, would you be able to let us know where on the source code this is
being set, so that we can try changing it and recompile ACS to turn off the
feature?

If it's possible, how would be the impact to CloudStack operations in
general? May I know what was the original purpose the limitation is being
put in the first place?

Thanks for the workaround recommendation -- will forward to our application
vendor to see if the app can be fine-tuned following your recommendation.

Looking forward to your reply, thank you.

Cheers.
